Question

A cookie company packages its cookies in rectangular prism boxes designed with square bases that have both a length and a width of 4in. less than the height of the box. Which polynomial below represents the volume of a box with height x inches


V=x(x+4)2


V=x(x−4)2


V=x(x−4)


V=2x(x+4)

Answer 1

Its B V=x(x−4)2 because x is the height, so x-4 is the length and also the width since length and a width of 4in. less than the height.
So L = x-4, W = x-4, H = x


Volume = length * width * height

V = L * W * H

V = (x-4)*(x-4)*x

V=x(x−4)2

Answer 2

thank you.
